Analyzer Instruction Manual, 02417, Rev. D
4.3 I/O Hardware Interface
4.3.1 RS-232 Interface
The M100AH uses the RS-232 communications protocol to allow the instrument to be connected
to a variety of computer based equipment. RS-232 has been used for many years and is well
documented. Generally, every manufacturer observes the signal and timing requirements of the
protocol very carefully.
Data Communications Software for a PC: You will need to purchase a software package so
your computer can transmit and receive on its serial port. There are many such programs, we use
PROCOMM at TELEDYNE API. Once you set up the variables in PROCOMM and your wiring
connections are correct, you will be able to communicate with the analyzer. Make sure the
analyzer is set up for 2400 baud (SETUP-MORE-COMM-BAUD) and that PROCOMM is set up
as described in the "RS-232 Pin Assignments" Figure 4-3.
